The Raspberry Pi's USB ports cannot provide enough current for high-power 500mA devices. If there are errors with enumeration, then there are a few usual suspects: The first will print out all devices attached to USB, whether they are actually recognised or not, and the second will print out the kernel message buffer (which can be quite big after booting: try doing sudo dmesg -C then plug in your device and retype dmesg to see new messages).

There are two commands that can be entered into a terminal for this: lsusb and dmesg. If a device doesn't work, then the first step is to see if it is detected at all. If you are using a different distro on the Pi, then you should check around the distro's website or guides to see how to update it. You should use sudo apt-get update & sudo apt-get upgrade to get the latest firmware and kernel that will contain many patches not present in the default installs of Raspbian. Work on the USB driver and kernel happens frequently. The rest of the steps come from this article and should be tried next. Raspbian and mount the system image on the SD card afterįormatting it, and seeing if the mouse will work with Raspbian vs

I can't move forward with out keyboard or mouse. I don't even see the lights on Keyboard and Mouse. I tried several times but when ever I connect the board with the power supply, it doesn't detect the keyboard and the mouse. I am using NOOBS ( ) and have it in the SDCARD. I also bought the CanaKit 5V 2.5A Raspberry Pi 3 Power Supply ( ).
